Description

Technical Field

[0001] This utility model relates to the technical field of engineering surveying instruments, and in particular to a slope measuring tool that is easy to read. Background Technology

[0002] Slope measurement is a crucial monitoring method; in civil engineering and construction projects, the slope gradient directly impacts design and construction plans. Slope measurement allows for the optimization of slope design and ensures construction quality. Regular slope measurements help identify potential maintenance problems, such as cracks and erosion, ensuring the long-term safety of the slope. Measuring the slope gradient helps assess slope stability, determining the risk of landslides or collapses, thus providing a basis for safety management.

[0003] Existing slope measurement tools generally measure the taper of the slope directly. When angles are needed, table conversion is required. Furthermore, the flatness of the slope surface can significantly affect the measurement results, leading to low measurement accuracy and impacting construction quality. Therefore, a device that can directly and accurately measure slope angles is needed. Utility Model Content

[0004] The purpose of this invention is to solve the above-mentioned problems and provide a slope measurement tool that is easy to read.

[0005] The technical solution of this utility model is: a slope measuring tool that is easy to read, comprising a housing, a standard measuring ruler, a spring tape measure, and a scale; the housing is cylindrical with a circular front; slots are provided on the circumferential side of the housing; a circular hole is provided in the center of the front of the housing; the standard measuring ruler is fixedly connected to the outer circumferential side of the housing and is tangent to the side of the housing; a take-up and release roller is provided inside the housing, and the take-up and release roller is coaxial with the housing; the spring tape measure is sleeved on the take-up and release roller, and the free end of the spring tape measure extends out of the housing through the slot; the scale is circular, located between the spring tape measure and the front of the housing, and is coaxial with the take-up and release roller; the scale is provided with graduations.

[0006] The scale on the dial represents angle values, and the dial rotates synchronously as the spring tape measure is pulled out; each length of the spring tape measure corresponds to a mark on the dial.

[0007] Preferably, a slide is connected to the outer side of the slot, which is tangent to the housing and perpendicular to the standard measuring ruler. This allows the angle of the spring measuring tape to be fixed, so that the standard measuring ruler, the spring measuring tape, and the slope form a right triangle, facilitating slope measurement.

[0008] Preferably, the extended end of the spring tape measure is provided with a pull handle, which is generally U-shaped. A clamp is provided at the end of the pull handle, and the clamp is fastened to the pull handle of the spring tape measure and fixedly connected by bolts. This prevents the extended end of the spring tape measure from being retracted into the housing and cannot be pulled out, and also protects the spring tape measure from friction with the ground during measurement.

[0009] Preferably, the standard measuring ruler is one meter long. With a one-meter measuring ruler, the slope's taper can be determined simply by reading the spring tape measure, making it much easier to use.

[0010] Preferably, a triangular pointer is provided on the upper part of the front side of the housing, which points to the scale of the dial. This allows for easy reading of the slope angle by aligning the pointer with the scale of the dial.

[0011] Preferably, the standard measuring ruler has a telescopic structure. This allows the standard measuring ruler to be retracted, facilitating the carrying and storage of the tool.

[0012] Furthermore, a bubble level is provided on the exterior of the housing; the bubble level is located at the junction of the housing and the standard measuring ruler. The bubble level ensures that the standard measuring ruler remains level during use, thereby improving the accuracy of the tool's measurements.

[0013] The beneficial effects of this utility model are as follows: The slope measuring tool of this utility model, which is easy to read, has the following advantages:

[0014] 1. This measuring tool can measure the angle of a slope without contacting the slope surface, and the measurement results will not be affected by the flatness of the slope surface;

[0015] 2. When measuring, the spring tape measure displays the slope's taper, allowing you to directly read the slope's inclination angle and taper without calculation or table lookup, making it convenient to use. Attached Figure Description

[0024] Example 1: See Figure 1-7 A slope measuring tool for easy reading includes a housing 1, a standard measuring ruler 2, a spring tape measure 3, and a dial 4. The housing 1 is cylindrical with a circular front. Slots are provided on the circumferential side of the housing 1. A circular hole is provided in the center of the front of the housing 1. The standard measuring ruler 2 is fixedly connected to the outer circumferential side of the housing 1 and is tangent to the side of the housing 1. A take-up and release roller 12 is provided inside the housing 1, and the take-up and release roller 12 is coaxial with the housing 1. The spring tape measure 3 is sleeved on the take-up and release roller 12, and the free end of the spring tape measure 3 extends out of the housing 1 through the slot. The dial 4 is circular, located between the spring tape measure 3 and the front of the housing 1, and is coaxial with the take-up and release roller 12. The dial 4 has graduations.

[0025] The scale on dial 4 is an angle value, and dial 4 can rotate synchronously as the spring tape measure 3 is pulled out; each length of the spring tape measure 3 corresponds to a scale on dial 4.

[0026] A slide rail 11 is connected to the outside of the slot. The slide rail 11 is tangent to the housing 1 and perpendicular to the standard measuring ruler 2. This allows the angle of the spring measuring tape 3 to be fixed, so that the standard measuring ruler 2, the spring measuring tape 3, and the slope form a right triangle, which facilitates the measurement of the slope.

[0027] The spring tape measure 3 has a pull handle 31 at its extended end. The pull handle 31 is generally U-shaped, and a clamp is provided at the end of the pull handle 31. The clamp is fastened to the pull handle 31 of the spring tape measure 3 and fixedly connected by bolts. This prevents the extended end of the spring tape measure 3 from being retracted into the housing 1 and unable to be pulled out, and also protects the spring tape measure 3 from friction with the ground during measurement.

[0028] In this embodiment, the pull handle 31 is connected to the spring tape measure 3 by rivets.

[0029] The standard measuring ruler 2 is one meter long. With the standard measuring ruler 2 being one meter long, the slope's taper can be determined simply by reading the spring tape measure 3, making it much easier to use.

[0030] A triangular pointer 13 is provided on the upper front of the housing 1, which points to the scale of the dial 4. The triangular pointer 13 corresponds to the scale of the dial 4, making it easy to read the angle of the slope.

[0031] The standard measuring ruler 2 has a telescopic structure. It can be retracted, making the tool easy to carry and store.

[0032] A bubble level 5 is provided on the outside of the housing 1; the bubble level 5 is located at the junction of the housing 1 and the standard measuring ruler 2. The bubble level 5 ensures that the standard measuring ruler 2 remains horizontal during use, thereby improving the accuracy of the tool's measurement.

[0033] The working principle of this embodiment is as follows: When the standard measuring ruler 2 is horizontally attached to the slope and the pull handle 31 at the end of the spring tape measure 3 is vertically lowered to the slope, the spring tape measure 3, the standard measuring ruler 2 and the slope form a right triangle. At this time, the ratio of the reading of the spring tape measure 3 to the length (1m) of the standard measuring ruler 2 is the taper of the slope (or the tan value of the slope inclination angle). The angle of the slope can then be read by observing the scale on the dial 4.

[0034] The usage method of this embodiment includes the following steps:

[0035] ① Extend the standard measuring ruler 2 and place it against the slope;

[0036] ② Pull out the pull handle 31 of the spring tape measure 3 and adjust the position of the pull handle 31 so that it rests on the slope;

[0037] ③ Observe bubble 5 and place the standard measuring ruler 2 horizontally;

[0038] ④ Observe the scale, record the taper and inclination angle of the slope, and the measurement is complete.

[0039] The slope angle can be measured multiple times to avoid large errors in the data.

[0040] Example 2: Example 2 is basically the same as Example 1, and the similarities will not be repeated. The difference is that a laser rangefinder is installed on the housing 1, and the laser rangefinder is pointed vertically at the ground. The laser rangefinder measures the height difference between the standard measuring ruler 2 and the ground, and directly displays the current slope's taper and inclination angle.
